NIST SP 800-171 Rev 2 to Rev 3 Crosswalk with DoD ODPs

As organizations prepare for the transition from NIST SP 800-171 Rev. 2 to Rev. 3, understanding how requirements have changed is critical. This crosswalk maps Rev. 2 controls to their Rev. 3 counterparts while incorporating Department of Defense Organization-Defined Parameters (ODPs) where applicable. The resource helps identify new, modified, and relocated requirements, making it easier to assess the impact of the revision on your cybersecurity program. Use this crosswalk to support gap assessments, update security documentation, and develop a roadmap for adopting NIST SP 800-171 Rev. 3.

Frequently asked questions

Find answers to common questions about K2 GRC's features, services, and more.
What are CMMC policy templates?
CMMC policy templates are pre-written, customizable documents that give defense contractors a starting point for the written policies required to handle Controlled Unclassified Information (CUI). Each template maps to a specific CMMC domain and covers the rules, responsibilities, and procedures your organization needs to define for compliance.
Do I need written policies to comply with CMMC?
Yes. Documented policies are a foundational requirement regardless of your CMMC level. Assessors and auditors expect written evidence that your organization has defined and communicated its approach to cybersecurity across every applicable domain — not just that controls are technically in place.
Are these templates enough on their own?
Templates are a starting point, not a finish line. Each policy needs to be tailored to reflect how your organization actually operates, approved by leadership, and communicated to your team. A policy that doesn't match your real-world practices creates more risk than having no policy at all.
What is the difference between a CMMC policy and a procedure?
A policy defines what your organization does and why it's a high-level statement of intent. A procedure defines how you do it, or the step-by-step process. Both are required for CMMC compliance, but policies establish the foundation everything else is built on.
How do these policies relate to NIST SP 800-171?
CMMC Level 2 is built directly on NIST SP 800-171, which defines 110 security controls across 14 domains. These policy templates are written to align with those controls, so documenting them moves you forward on both CMMC and your broader 800-171 compliance obligations simultaneously.
How often should CMMC policies be reviewed?
Most assessors expect policies to be reviewed at least annually, or whenever there is a significant change to your environment, personnel, or systems. Keeping policies dated, versioned, and tied to a review cycle is a simple practice that carries significant weight during any compliance assessment.
